CHARTS AND DIAGRAMS
NOTES OF SCHEMATIC DIAGRAM
Safety precautions
The Components identified by the symbol are
critical for safety. For continued safety, replace saf ety
critical components only with manufacturer's recommended parts.
1. Units of components on the schematic diagram
Unless otherwise specified.
1) All resistance values are in ohm. 1/6 W, 1/8 W (refer to
parts list).
Chip resistors are 1/16 W.
K: KΩ (1000Ω), M: MΩ (1000KΩ)
2) All capacitance values are in µF, (P: PF).
3) All inductance values are in µ H, (m: mH).
4) All diodes are 1SS133, MA165 or 1N4148M (ref er to parts
list).
Note: The Parts Number, value and rated voltage etc. in
the Schematic Diagram are for references only.
When replacing the parts, refer to the Parts List.
2. Indications of control voltage
AUX : Active at high.
AUX or AUX(L) : Active at low.
4. Voltage measurement
1) Regulator (DC/DC CONV) circuits
REC : Colour bar signal.
PB : Alignment tape (Colour bar).
— : Unmeasurable or unnecessary to measure.
2) Indication on schematic diagram
Voltage Indications for REC and PB mode on the schematic diagram are as shown below.
REC mode
123
2.5
(5.0)
PB mode
1.8
PB and REC modes
(Voltage of PB and REC modes
are the same)
Note: If the voltages are not indicated on the schematic
diagram, refer to the voltage charts.
5. Signal path Symbols
The arrows indicate the signal path as follows.
NOTE : The arrow is DVC unique object.
Playback signal path
Playback and recording signal path
CIRCUIT BOARD NOTES
1. Foil and Component sides
1) Foil side (B side) :
Parts on the foil side seen from foil face (pattern face)
are indicated.
2) Component side (A side) :
Parts on the component side seen from component face
(parts face) indicated.
2. Parts location guides
Parts location are indicated by guide scale on the circuit board.
REF No.
IC101 B C 6 A
(A : Component side)
D : Discrete component)
B : Foil side
C : Chip component
Note: For g eneral information in service manual, please
refer to the Service Manual of GENERAL INFORMATION Edition 4 No. 82054D (January 1994).
